Mycielskian图的对称参数

Symmetry Parameters for Mycielskian Graphs

Debra Boutin, Sally Cockburn, Lauren Keough, Sarah Loeb, K. E. Perry, Puck Rombach

摘要:

Mycielskian构造(记为$μ(G)$)将有限单图$G$转化为团数相同但色数较大的图.广义Mycielskian构造,记作$μ_t(G)$,把$G$带到一个具有相同色数但奇围长更大的图。在本章中,我们根据$G$的相同参数来研究$μ(G)$和$μ_t(G)$的对称参数。这些对称性参数包括判定数、区分数和区分代价。

英文摘要:

The Mycielskian construction, denoted $μ(G)$, takes a finite simple graph $G$ to a larger graph with of the same clique number but larger chromatic number. The generalized Mycielskian construction, denoted $μ_t(G)$, takes $G$ to a larger graph with the same chromatic number but with larger odd girth. In this chapter we look at symmetry parameters of $μ(G)$ and $μ_t(G)$ in terms of the same parameters of $G$. These symmetry parameters include determining number, distinguishing number, and cost of distinguishing.
